BUBTEN L. BARTON, OF WENDELL, IDAHO.

CULTIVATOR.

Specification of Letters Patent.

Application filed May 3, 1917. Serial No. 166,198.

To all whom it may concern:

Be it known that I, B'urarnn L. BARTON, acitizen of the United States, residing at lVendell, in the county of Gooding and State of Idaho, have invented new and useful Improvements in Cultivators, of which the following is a specification.

My present invention has relation to cultivators and other land-working machines; and it contemplates the provision of a simple, easily operated and light draft machine, designed and adapted for corrugating land planted with alfalfa and other crops as well as virgin land in such manner as to assure adequate distribution of water and thorough irri 'ation of the land.

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this'speoification, in which:

Figure 1 is a top plan view, partly broken, of the land-workingmachine constituting the best practical embodiment of my invention that I have as yet devised.

Fig. 2 is a side elevation of the same.

Fig. 3 is a rear end elevation of the machine.

Fig. 4 is an enlarged detail view illustrative of the manner of attaching each of the steel points to its complementary channelform shoe.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel machine comprises a platform-like body 1 which is preferably, though not necessarily, of wood.

Fixed to the upper side of the said body or platform 1 and extending forwardly and upwardly therefrom are forwardly converged metallic straps 2 which are pivotally connected at 2 to metallic uprights 3 and a wooden tongue 4, the latter being interposed between the metallic uprights, and being adapted to be swung vertically on the center 2 for the purpose hereinafter set forth. The said tongue 4 is shown as provided with a hammer strap, Figs. 1 and 2,

for the connection of a double tree (not illustrated) though it is to be understood that the double tree may be connected with the tongue in any other approved manner without affecting my invention.

Fixed to and rising from the platformlike body 1 and arranged adjacent to the rear end thereof is a loop-shaped upright 5. This upright receives, guides and braces the rear end of the tongue in the vertical movements thereof, and it also serves to support and brace the seat bar 6 which is connected at its forward end between the uprights 3 and is equipped at 7 with a drivers seat of sheet steel or other suitable material.

Fixed to and rising from the body 1, at one side of the upright 5, is a segmental rack 12, and journaled in transverse bearings 8 on the body is a transversely-disposed rock shaft which is provided intermediate the said bearings with a loopshaped crank 9, and is also provided at its ends with a hand lever 11 equipped with a detent for the purpose of adjustably fixing it with respect to the rack. The transverse portion of the crank 9 is arranged and movable in the strap bearing 10 at the underside of the rear portion of the tongue, and consequently it will be manifest that rocking of the lever 11 will be attended by upward and downward movements of the rear portion of the tongue; also, that when the detent of lever 11 is seated in one of the depressions of the rack 12, thetongue 4 will be adjustably fixed with respect to the body 1.

Arranged longitudinally at the underside of the body 1 and suitably spaced apart are shoes 14, of channel form in cross-section. These shoes are preferably of cast iron and are fixed to the body 1 in any manner compatible with the purpose of my invention. At their forward ends the shoes 14 are equipped with tempered steel points 16 which have the upwardly and rearwardly inclined portions 15 for the passage of connecting bolts 19 and the lower rearwardly extending portions 17 for the passage of connecting bolts 18, the latter being carried through the channel-form shoes 14 and suitably connected to the body 1 and the braces 2.

As will be understood by comparison of Figs. 1, 2 and 4, the construction, shape and proportional size of the points 16 are such that they readily enter and leave the ground and are also adapted to divide alfalfa roots with a view to making continuous furrows for the shoes 14 to travel in, and this in such manner that but little draft is imposed on the team drawing the machine.

Patented Mar. 5, 1918.-

In operation when the lever 11 is adjusted forwardly the machine is so manipulated in all of its parts that the points 16 are thrust downwardly so as to enter or penetrate the ground, and when the machine is operated with the points 16 disposed as stated the said points will manifestly cause the shoes 14: to follow in the furrows made by the points with the result that channels are left after the machine through which water will be distributed over the land.

lVhen the lever 11 is adjusted rearwardly, the points 16 are raised and thereby enabled to work out of the ground, with the result that corrugating of the land is stopped as is desirable, for instance, when the machine is being turned at the end of the field.

It will be gathered from the foregoing that my novel machine is simple and inexpensive in construction and is light in weight and; draft; also, that the machine as a whole is well adapted to withstand the rough usage to which machines of corresponding character are ordinarily subjected.

Having described my invention, what I claim and desire to secure by Letters Patcut, is:

1. In a ground working machine, the combination of a body, longitudinally-disposed spaced shoes, of channel-form in cross-section, fixed with respect to the body at the underside thereof, points fixed to the forward ends of the said shoes, a tongue connected with the body, and means connected with the body and the tongue and construct ed and arranged to adjust the points of the shoes and also constructed and arranged to adjustably fix the points in the positions in which they are placed.

2. In aground working machine, the combination of a body, longitudinally-spaced shoes, of channel form in cross section, fixed with respect to the body at the underside thereof, points fixed to the forward ends of said shoes, braces fixed to and extending forwardly of the body, a tongue pivotally connected at an intermediate point of its length to saidbraces and arranged to be swung vertically on said pivot, and means on the body and tongue for adjusting and adjustably fixing each with respect to the other.

3. In a ground working machine, the combination of a body, longitudinal, spaced shoes fixed to the body at the underside thereof, said shoes being of channel-form in crosssection and having points at their forward ends, braces fixed to and extending upwardly and forwardly from the body, a vertically swinging tongue pivoted at an intermediate point of its length on said braces, uprights extending upwardly from the braces and tongue, an upright loop fixed on the body and receiving the rear end of the tongue, a bar connected to said uprights and resting on and connected to said loop and extending in rear of the loop and provided with a seat, a segmental rack fixed on the body, a transverse rock shaft journaled in hearings on the body and having a crank and also having a lever equipped with means for engaging the rack, and a strap bearing on the rear portion of the tongue and receiving the crank of the shaft.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
